Low ejection fraction, on the other hand, is an ejection fraction that is lower than the normal percentage. This is mainly due to abnormal enlargement of the ventricles and reduced ventricular function. Patients presenting with cardiac insufficiency often have a reduced ejection fraction. The chance of sudden death from malignant arrhythmias is greatly increased when the ejection fraction is reduced to less than 35%. What are the contraindications for patients with low ejection fraction in terms of diet? 1. Avoid spicy and irritating foods. 2, avoid greasy food. 3.Appropriately limit the intake of protein and caloric energy.
